: Before I got it for a short time, I sent a simple report on M11 Plus on Weibo. After a period of detailed work, I was in a state of commenting while using it. As a result, Apple Music had not yet pushed it when it was written. The writing was almost over, but Apple officially pushed it... Yes, before making M11 Plus, Feiao was already an MFi brand certified by Apple, before that, Apple Music was laid out in Feiao market. This step is really very cutting-edge. Now, digital master tape? ALAC? You can use the APP directly without other equipment. All right, let's not talk too much, let's go to the text.

Feiao's blockbuster product M11 Plus LTD arrived as promised in 2021. This time it is not only an upgrade of M11 Pro, but also a new generation of design from the appearance. The main control chip uses Qualcomm Xiaolong 660 and is matched with customized and optimized Android 10, which makes a qualitative leap in the expansion of functionality. Friends who are familiar with HiFi music equipment should have heard of last year's AKM fire, but this time, feiao tried his best to bring us the real limited DAC chip AK4497, the classic voice, never say goodbye. Of course, in addition to these high-quality hardware blessing, user experience is also Feiao's constant pursuit. Now, let's savor it carefully, which will eventually become the classic M11 Plus LTD.

Appearance

appearance, it can be seen that the M11 Plus LTD Feiao has exhausted its thoughts this time. It is a thorough innovation, not a slight improvement. It is quite different from the previous product M11 Pro, which can be described as a sincere work.

be called a sincere work from the appearance change? First of all, M11 Plus LTD is the first design language to carry a new generation of Feiao-honeycomb hexagonal design, we can easily see that this is a signal, is the next new series of products of the common design concept, and M11 Plus is very clear as the first to try the first, the battle of the vanguard, it can be seen that its product positioning is very important.

, when we picked up M11 Plus, we saw the 5.5-inch 18:9 gold ratio full screen. As a portable HiFi music player, the full screen with such a ratio is not only for the beauty and design of the internal UI, but also for the seamless connection between the user's switching between the mobile phone and the HiFi music player. When we put down our mobile phone and use a professional HiFi music player, I will not feel any backwardness and discomfort, and my friendliness to burning friends or novice friends will greatly increase. In addition, it also provides basic support for the experience of multiple entertainment functions.

this is the highlight of this upgrade. Feiao pioneered the integrated design of key touch. Compared with the previous product M11 Pro, it not only looks more integrated in the whole machine shape, but also provides an unprecedented operation mode in the use experience. The key is the traditional volume up and down, and the volume can be adjusted on the panel according to the degree of finger sliding, which is very convenient.

Talk about the mainstream volume adjustment methods in detail:

adjustment-slide the screen volume bar. In the past, we pressed the volume key for a long time or rotated at a large angle. Now we have a full touch screen and 0-100 is completed instantly.

precise adjustment-volume addition and subtraction key, this is the oldest adjustment method, and it is indeed the most effective method, but because its own kernel idea is still "1,-1", this method needs to be very, very accurate The use is the most reasonable, but it is slightly clumsy to add and subtract amplitude in this way, and it cannot increase the volume quickly, let the ear sense of hearing feel change; the roller core thinking is the same, the way of expression is different.

small range adjustment-this is the most suitable adjustment method for our natural senses. In our life, the situation of 0-100 or 1-1 is not the most commonly used, because what we adjust music and audio changes according to our own hearing. After a large adjustment, it is often rarely changed. The 1-1 situation is also used only when it needs to be very accurate, and fine adjustment will not have much change in hearing. However, a small adjustment just takes into account the advantages of both. Based on the combination of software and hardware, it prevents the situation of large-scale ear explosion and increases the speed of volume change. Fast, safe and effective listening change is the most ideal situation, which is the first idea of M11 Plus and has won the hearts of the people.

tip: Through the test, the volume changes under the condition of a single thumb slide-boys 4-6 squares; Girls 2-4 squares.

If the microblog has a watermark, slide it directly on the panel.

M11 Plus follows Feiao's classic interface. The 2.5/4.4mm balanced interface has been retained, and the 3.5mm single-ended interface still exists. The original USB decoding interface is the highlight of Feiao's characteristics. While charging through this interface, it can also link computers, cooperate with rich earphone ports, open USB mode, and immediately transform M11 Plus into an independent DAC decoding earphone. It has USB Audio output function and can be directly used as a high, further show its excellent comprehensiveness, so that you can get a better audio experience no matter what the situation is. It can be described as the best fishing companion in the kitchen under the hall.

on the whole, the lines are hard and sharp, with sharp edges and corners, showing the beauty of rigidity everywhere. And under the design of the innovative key touch module, the overall shape is integrated. The side breathing lamp of the finishing touch shows the beauty of light luxury and simplicity. It is easy to accompany you to any scene. This time there is a stainless steel version of color matching, making LTD more LTD.

, I would like to talk about the core aspects of the new exterior design. The visual sensory level must correspond to the structural modeling inside the fuselage. Here, let's talk about the core of this change: in the current industrial system, structure serves modeling, and modeling cannot be separated from structure. The value of M11 Plus is that the brand-new design language is not simply the appearance of kung fu, but Feiao insists on completing all the innovations from the inside to the outside, and the internal structure is bound to undergo major changes. It is mainly reflected in the key module. In order to better heat dissipation and space utilization, the traditional roller-type mechanical structure will occupy a large horizontal space inside the fuselage, which is inevitably not conducive to the release of high-specification chip performance and heat generation. Therefore, it is abandoned; this time the innovative idea of integrating the left touch button can greatly optimize the internal space, but it also adds a lot of difficulty in assembly, therefore, Feiao skillfully uses the side T-slot steel to link the circuit through FPC to shrink the lateral width of the internal space. Similarly, the right side also follows the same design idea, while completely retaining the switching functions of pause, previous and next, it also adds HOLD lock keys to prevent the possibility of accidental touch. Such a complex and ingenious process can not only optimize heat dissipation, but also plug a larger capacity battery, from the 5200 mA to the 6000 mA, so that the battery life is further extended; as mentioned earlier, such optimization makes the shape, structure, and internal The layout of components has reached the extreme, and the seemingly simple changes have actually gone through the thinking of engineers day and night; the work of the heart, the product of sincerity, this is self-evident, in order to improve the user's experience, Feiao has no energy to spare.

Products

product specifications, let's first quickly preview the main parameters of M11 Plus: out-of-print DAC decoding chip AK4497EQ * 2, main control chip Qualcomm Xiaolong 660, newly customized and optimized Android 10, highest-end earmuff architecture THX-AAA78 * 2, new DAPS digital audio purification system, with dual NDK femtosecond crystal oscillator and self-developed fourth-generation FPGA support, Hi-Res small gold standard certification, supporting global MQA-8 times expansion, bluetooth 5.0 is bidirectional and supports LDAC/AAC/SBC/aptX aptXHD transmitter, the battery capacity is increased to 6000mAn, the output power is up to 588mW, and the third-speed gain adjustment is supported.

industry bad news, especially audio industry

fans who are familiar with HiFi must be aware of the above news. A fire has destroyed many key products and production lines of AKM (Asahi Kasei Microelectronics Co., Ltd.). As the flagship DAC decoding chip of the audio IC factory, AK4497 AK4499, is among them and will not be able to supply such chips normally. In other words, such a blow is a disaster for any manufacturer that makes HiFi players. Now a piece of AK4497 on the market is still rising to 200 US dollars. Many manufacturers' original plans for new products have been ruined. The positioning and pricing of products and the previous research and development investment have turned into dark clouds.

of course, this blow to Feiao was also caught off guard. Unable to supply normally, in the face of the price cost of chips that are flying up, many of the original plans had to become a monk halfway-looking for another way. Even in this situation, it seems that all this is destined to be classic, and perhaps there are some fate elements. JAMES talked about it on Weibo before that AKM suffered a serious fire in some parts, and it was just another part of the finished product inventory on the same floor that was preserved. Among them, the orders signed by Feiao and the inventory in the hands of agents later raised more than 14000 pieces. However, M11Plus each machine needs to carry 2 chips, we can basically calculate that the total number of M11 Plus is about 7000. And because of the need to face global supply, the M11 Plus quota in China is only about 2000 units. Now, everyone should understand why I said earlier that this will eventually become a classic player. You can also probably know why M11 Plus has more LTD as the successor model of M11 Pro, because its birth is destined to be limited and classic.

with the shortage of audio DAC decoding chips, let's see what upgrades have been brought to us about our overall operating experience. First of all, this time we have brought Qualcomm 660 chips, 4G RAM 64G ROM configuration on HiFi player is smooth and energy-saving, listening to songs, watching videos and playing games have good experiences, and so on... still can play games ??? HiFi games? Comfortable!

After introducing the two core sections, Feiao, as a professional HiFi player manufacturer, is an inevitable mission to pursue the ultimate audio quality. Since 2016, it has been cooperating with THX Company of the United States to use its amplifier technology. Briefly, the core of this technology is feed-forward error correction and 'achromat' sound-free amplification signal architecture. The M11 Plus is equipped with the highest-level THX-AAA-78 architecture in the portable architecture, with Feiao's fourth generation FPGA and two customized Japanese NDK crystal oscillators. From hardware support to software architecture, from audio accuracy and amplification to purity and restoration of audio stream, every detail is properly considered by engineers, and the place where materials are used carefully is not found, but can be reflected in the subtle details of sound.

when it comes to using feelings, this is what our consumers can actually feel most. The hardware upgrade in exchange for software stride forward. This time the whole system was upgraded to Android 10, but the Android system of a HiFi player is not used directly like a mobile phone and needs heavy adaptation. This process can also be understood as re-customization. M11 Plus has more than 130 customized UI elements. The result of designers and Cheng Xuyuan balding day and night is-support for dark mode, more convenient gesture operation, 5 usage modes, the third generation ALL TO DSD, support third-party streaming media platforms, such as APPLE MUSIC music. Among them, we need to focus on 5 usage modes and third-party APPLE MUSIC music.

These five modes are: Android mode, pure tone mode, Bluetooth mode, USB mode and car mode. Android mode, the most conventional mode, all the functions of the system are at a glance, which is no different from operating the mobile phone, also known as watching video and playing game path; pure tone mode, entering the player mode, as the name implies; Bluetooth mode, this is the hottest mode at the moment. As a professional player, from the perspective of consumers, of course, I hope it can play all its functions, squeeze the performance of the last drop-make full use of the high-specification chip and architecture introduced earlier, then Feiao naturally takes this into account. Feiao designs a two-way Bluetooth 5.0 in M11 Plus. The transmitter supports SBC/AAC/aptX,aptX HD/LDAC in full format, and the receiver supports SBC/AAC/LDAC without loss. Here, it is mentioned that the aptX format cannot be used, feiao specially designed the Air Play mode for it, which can be regarded as a compensation for a small regret. USB mode, after USB is connected to the computer, the computer is used as the sound source, and the middle decoding and amplification are completed by M11 Plus. Whether it is Foobar listening to songs, video editing, recording monitoring, it needs to ponder those details, it can be perfectly competent. In addition, M11 Plus is also known as fishing artifact in the office. Car-mounted mode, which Feiao took the lead in innovating in China many years ago, has been in use today and is deeply loved by everyone. For the audio decoding and amplification in the car, it has been upgraded to a very high level, especially for the friends of the old car, there is no worry about the host in the car, only the AUX port is needed, and the 3.5mm interface is plugged in. M11 Plus immediately incarnates the audio host in the car. The fresh content in the mobile phone will no longer be missed. The car will be started when the car is started, and the car will!

? Listen to Apple's digital master tape with such a high-specification chip architecture; Just ask you, are you comfortable?

use is relatively cutting-edge: third-party streaming media software support, especially this year's APPLE MUSIC support. Apple's system has always been slightly inferior to the Android camp in audio format, such as LDAC or aptX, which is not available for high-definition digital streaming. Apple itself is also audio in ALAC format, but it has been tepid. This time APPLE MUSIC will support Dolby panoramic sound, lossless and high resolution lossless playback from June. This also tells us that according to Apple's strength, it is not difficult to increase 16Bit 44.1KHz to 24Bit192 KHz now, and Bluetooth will use a format with a larger amount of data in the future. As an authorized brand of Apple MFi, Feiao is the first to provide APPLE MUSIC APP in Feiao application market, which is a very cutting-edge thing.

, just a few days before I wrote the article, Apple Music had not officially pushed it. Now that it has been officially pushed, why need extra equipment? This is the best! There is no need to connect anything, one machine is all. Perfect support for ALAC.

Summary

Shinji-kun, is that you?

Finally, it is time to summarize. I believe that after such a lengthy introduction, I have a general understanding of this professional HiFi music player. We can see that under the pressure of chip supply, Feiao insisted on the pursuit of high-quality HiFi and did not stop. He gave us AK4497 chips without reservation. Under the premise of soaring cost, the price did not change greatly, so that consumers could not accept it. On the basis of limited quantity, we understood the meaning of out-of-print. Before putting into production, we also saw the painstaking efforts of designers and engineers, determined to create a classic after many years, Mu Ran will look back and see this classic.

at the current price of 200 US dollars, one AK4497 chip will cost more than 2000 if two are carried on M11 Plus. Crazy stacking of various flagship hardware and technologies, brand-new design language; M11 Plus, which carries painstaking efforts and high hopes, will eventually become an immortal chapter. With thick heart, it is worth collecting for both the first and the old.

----------------------------- Tactical dividing line-----------------------------

a little advice

found a small area that needs to be improved and upgraded. When we use Bluetooth mode and USB mode, the player is often in static scenes such as desktop and special base. At this time, we are more likely to stand still and only touch the screen to operate. However, the next song and the pause function button are not available on these two interactive pages. At this time, you need to pick up the player and adjust it. This may add one more step to wake up the machine by hand. I hope the software engineer can add it in this mode next time and adjust it directly without extra actions.

. I'll see you next time ~
